Genistein Stimulates Insulin Sensitivity Through Gut Microbiota

The investigators included 45 participants who met the following inclusion criteria: adults between 20 and 60 years of age with a diagnosis of MetS, HOMA index greater than 2.5, BMI ≥30 and ≤ 40 kg / m2 and who signed the consent letter. Patients who had any added pathology, pregnancy, smoking or consumed medications were excluded. Once the letter of informed consent was accepted, the patients were assigned to the respective treatment group. These individuals were advised to consume the recommended diet for subjects with MetS according to the guidelines of the ATPIII. Participants were randomly distributed to consume a) placebo treatment or b) genistein capsules (50 mg/day). The participants were followed for 2 months. In the previsit, informed consent letters were given, and blood samples were taken to evaluate glucose concentration, lipid profile, lipopolysaccharide and serum insulin. Also determined blood pressure, body weight, height, body composition and gut microbiota. The presence of insulin resistance was determined by means of the HOMA-IR index and by an oral glucose tolerance test. After 2 months, the same variables were assessed, and an expert surgeon in the operating room performed a vastus lateralis muscle biopsy, then RNA extraction and gene expression microarray assay was performed
